GEHL RS10-44, RS10-55, RS12-42, RS6-42, RS8-42 2013 Parts Catalog

You are holding a parts order in your hand, or maybe staring at a hydraulic leak that needs an O-ring you can’t identify. The wrong part means a week of downtime, or worse – a safety risk on a telescopic handler that lifts tons. I’ve been there. That’s why I only use OEM documentation when I’m ordering parts for the GEHL RS series. This 326-page GEHL RS10-44, RS10-55, RS12-42, RS6-42, RS8-42 2013 Parts Catalog is the factory-issued book, not some aftermarket scan. It tells you exactly which O-ring goes where, what torque to use on a hydraulic adapter, and which filter element fits your machine. No guessing.

O-Ring Tables and Torque Guides – Where the Real Specs Live

Inside the Reference section you’ll find four separate torque guides: O-Ring Tables, Adapter Torque Guide, Metric Bolt Torque Guide, and SAE Bolt Torque Guide. These are the specs that keep a boom from dropping or a hose from blowing. The O-Ring table lists every dash size and cross-section used on these machines. Without that table, you’re measuring with calipers and hoping – and I’ve seen too many guys use a too-thin O-ring that squirts oil under pressure. The torque tables give you foot-pounds for every bolt grade and thread pitch, SAE and metric. That’s the difference between a joint that stays tight and one that leaks after 50 hours.

Filters, Fuses, Decals – Small Parts That Stop Big Jobs

The manual starts with a Filters section (page 6 in the TOC), then Fuses, then Decals. You might think a decal is just a sticker. But a missing capacity decal on the boom could cause an overload. A wrong fuse rating can fry a control module. This manual lists the OEM part numbers for every filter element – hydraulic, fuel, air – and the exact fuse amperage for each circuit. When a customer brings in an RS8-42 that won’t start, the first thing I check is the fuse map. This catalog has it.

Numerical Index: Why the Index Saves Your Saturday

Page 1 and 2 of the manual show the table of contents and serial number breakdown. But the real time-saver is the Numerical Index. It lists every part number in numeric order with the page where that part appears. You have a part that fell off the machine? Write down the number stamped on it, flip to the index, and you’re looking at the exploded diagram in 30 seconds. No flipping through 300 pages. The manual also has a Subject Index if you don’t have the number but know what the part does.

Subject Index and Model Verification – Don’t Order for the Wrong Machine

Page 2 of this manual tells you exactly how to read the serial number plate. The model, year code, month, and unit number are all there. For example, RS10-44 with serial beginning 90191. Order a part for an RS6-42 when you have an RS10-55? That can happen if you skip this step. The parts lists have page markers that show which models each page covers – RS6 and RS8 models only, or RS10 and RS12 only. Check the header. This catalog covers the RS series except RS5-19 and RS6-34. If you own one of those, you need a different manual. See GEHL RS10-44 RS10-55 RS12-42 2010 Parts Catalog for earlier models, or the GEHL RS10-44 2009 Parts Catalog for that specific machine. The GEHL RS6-42 RS8-42 RS8-44 2008 Parts Catalog covers older versions.

Factory Torque Specs vs. Aftermarket Guesses – A Lifesaving Difference

I’ve had a tech use a generic torque chart for a metric bolt on a GEHL adapter flange. The bolt stripped at 80 ft-lb when the factory spec called for 65 ft-lb. That repair cost us an afternoon. The SAE and Metric Bolt Torque Guides in this manual are factory-verified for the bolt grades used on these machines. The Adapter Torque Guide gives you specific values for JIC, ORFS, and other hydraulic fittings. Using the wrong torque on a steering cylinder mount can cause a failure at the worst time. For background on diesel engine fundamentals, see this Wikipedia article on diesel engines. But for parts and torque, stick with the OEM book.

Does this manual cover the RS5-19 models?

No. The introduction explicitly states this manual covers all RS models except RS5-19 and RS6-34. You need a separate parts catalog for those.

What torque values are listed?

The Reference section includes a Metric Bolt Torque Guide, SAE Bolt Torque Guide, Adapter Torque Guide, and O-Ring Tables. The tables give foot-pounds for bolts from M4 to M30 and SAE grades 2, 5, and 8, plus adapter torque for common hydraulic fittings.

How do I find the right part number if I only have a description?

Use the Subject Index at the back of the manual. It groups parts by function – for example “Steering cylinder” or “Hydraulic pump”. Then cross-reference the page number with the model-specific page markers. You can also look up the serial number breakdown on page 2 to confirm your machine.

Is this a genuine OEM print or a reprint?

This is a factory OEM GEHL Parts Catalog with form number 50960015, revision C, dated December 2013. It is a scanned PDF of the original printed manual, not a third-party compilation. All diagrams, part numbers, and torque tables are identical to what the dealer would use.

You need a parts manual that matches your machine’s exact specs. The 326 pages in this catalog cover the RS6-42, RS8-42/44, RS10-44/55, and RS12-42 from serial numbers listed on page 1. Access the Factory Manual now and stop wasting time on wrong parts and guesswork torque.
